NaturalPoint's hands free mouse that
covered by Slashdot some time ago.
It seems to work as advertised, using a camera to track your head and replace
your mouse, but with a lot of caveats. Definitely worth a look for us truly
lazy folks.

You're right about there being less motion in the head near the edges, however, less motion is required to describe the movements near the edge. A user's head tilting 45 degrees from orthogonal to the center of the screen describes a circle of radius 5", if her face is 5" from the screen. (Too close, I know, but just for sake of easy math.) Add another 45 degrees to that, and she's 90 degrees from the screen, defining an infinite plane, parallel to the plane of the monitor. Infinity is what we like to call "far," Russ.
Now, those are just two points, but I think you can get it from there... very small changes at the edges translate into large motions over the plane (in this case, the monitor).
This may mean that there's a potential problem with resolution at the edges, but not with motion or speed.
Alot of great applications besides for lazy people (Score:2, Insightful)
